Paperiliittimet

Paperiliittimet, often translated as paper fasteners or paper clips, are simple mechanical devices used to hold sheets of paper together temporarily. They are typically made from bent wire, commonly steel, which is coated to prevent rust. The most common design involves a double-oval shape, though variations exist. This design allows the clip to be easily attached and removed without damaging the paper.

The history of the paper clip is somewhat debated, with numerous patents issued for various designs in the late 19th and early 20th centuries. However, the bent wire clip as we know it today is often attributed to Johan Vaaler, a Norwegian inventor who patented a design in 1899, though his version was reportedly less practical than others. Despite this, the "clip" became a symbol of Norwegian resistance during World War II, worn as a sign of unity and solidarity against the Nazi occupation, as it was seen as a symbol of sticking together.

Paper clips are ubiquitous in offices, schools, and homes worldwide. Their primary function is to organize documents, prevent misplacement, and facilitate easy browsing of multiple pages. Beyond their intended use, people often find alternative applications for paper clips, such as resetting small electronic devices, picking locks, or as makeshift bookmarks. Their low cost and widespread availability make them a staple in stationery supplies.
